GEORGE NEVTON BALL, 0F ARGENTINE, MICHI lfAN, ASSIGNOR OF ONE- IIALF TO SYLVESTER SMITH, OF SAME PLACE.

WINDMILL.

SPECIFICATION forming part Of Letters Patent N0. 426,162, dated April 22, 1890.

Application filed October 20, 1888. Renewed March 25, 1890. Serial No. 345,257. (No model.)

To all whom t may concern:

Be it known that I, GEORGE NEWTON BALL, a citizen of the United States, residing at Argentine, in the county of Genesee and State of Michigan, have invented a new and useful Improvement in XVindmills, of which the following is a specification.

The invention relates to windmills having horizontal wheels; and it consists in the construction and novel combination of parts hereinafter described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a perspective view of a windmill embodying the invention. Fig. 2 is a central vertical section thereof. Fig. 3 is a plan view of the upper part of the windmill with the roof removed. Fig. 4 is a detail view of one of the vertical standards, showing the manner of raising the cylindrical housing. Fig'. 5 is a detail view of pitman H and block I.

Referring to the drawings by letter, A designates the mill-tower, of the usual pyramidal shape and having the four upwardly-converging corner-posts a, to which are secured at their upper ends the vertical standards B, having their outer surfaces rounded, as shown, on the arc of a circle the center of which lies in the axis of the tower. The said standards are crowned by a conical roof G, the edge of which projects outward and downward, forming the eaves c.

D is the wind-wheel, composed of the four equidistant sections d, standing at right angles'to each other, and the shaft E, journaled above and below at the intersections of crossbeams e, connecting diagonally the tops of the standards and the tops of the end posts. The sect-ions CZ are of plate metal, preferably, and each is bent into an approximately semicylindrical shape and has its central part curved outward above and below to form a strengthening-rib (Z, that extends outward from the shaft E.

F F are collars secured to the shaft E at suitable points and having the inner lapping corners of the sections (l lirmly secured to their inner surfaces. The lower end of the shaft E projects below its bearing, and is squared for insertion in a squared recess in the upper end `of a vertical crank-shaft G,

the lower end of which is suitably stepped upon a cross-beam of the tower.

ll is a pitman standing outward from the crank gef the shaft G, and having a fork h at its outer end.

I is a block trunnioned at its ends in the arms of said fork and having a central bearing-opening.

.l is a crank-lever pivotcd at its angle upon a cross-beam of the tower, and with the end of its vertical arm seated in the bearing of the block I, which arm works in the notch or slot of a guide-bar j, secured at a proper point tothe tower. rlhe end of the horizontal and preferably shorter arm of the cranklever is loosely connected by a pitman or otherwise to the upper end of the plungerrod K, which reciprocates in suitable guides secured to the Itower. The said plunger-rod may, by means ot suitable connective mechanism, run a pump, a mill, or other machine.

L is a cylindrical housing, somewhatwider than the wind-wheel and adapted to slide up and down on the standards B, to the outer sides of which its curvature conforms. The said housing is provided on its interior, near its lower edge and at diametrically-opposite points, with staples l, situated near two diagonally-opposite standards.

M is a chain or rope with its ends secured to said staples, whence it passes up along the corresponding standards and over the pulleys m attached thereto, andthen down again along the standards to points below the wheel, its central portion extending across within the tower.

N is a wire secured at its upper end to the. middle of the chain and with its lower end within reach of the operator. By means of said chain and wire the housing may be pulled up until it is in contact with the eaves o and entirely surrounds the wheel, thereby cutting off the wind and stopping the operation ot the mill. When so raised, the lower end of the wire may bc attached to a cleat or other suitable detcnt secured to the tower.

Then it is desired to start the mill, the wire is released and the housing will descend below the wheel by gravity till its lower edge rests on the stop-supports O O, secured to the corner-posts.

Whatever wind there is in any direction IOC Will operate the mill, as the concave inner1 surfaces of the sections will hold the wind, While their convex outer surfaces deflect the same both upward and downward, so that said concave surfaces will move with the Wind and force the convex surfaces of the opposite sections against the same.

Having described my invention, I claim- The combination of the tower, the wheel arranged above the same and having a central shaft E, the crank-shaft G, having its lower end stepped on a cross-beam of the tower and its upper end engaging the lower end of the shaft E, the pitman H, projecting horizontally from the crank 0i the shaft G and having a fork 7L at its outer end, the

block I, trunnioned in said fork, the cranklever J pivoted at its angle upon a crossloealn of the tower and having the end of its longer vertical arm engaging the lolockV I, the plunger-,rod K, pivoted at its upper end to the end of the horizontal arm of said lever, and the slotted guide-bar j, secured to the tower and receiving the longer vertical arm of said lever, as speciied.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in presence of two Witnesses.

GEORGE NEVTON BALL.
